5.5.1 Product ID and Breaker Product ID
The Product ID and Breaker Product ID are transmitted in two reg-
isters, as shown in Table. Both registers must be accessed in one
operation, using Function Code 04.

Product ID/Breaker Product ID 6255 186E Encoded
The Product ID is encoded as follows:
•
Product ID = 3 – b15 .. b10 of Register Address 0x186F;
•
Communication Version = 1 – b9 .. b6 of Register Address
0x186F; and
•
Division Code = 35 – b5 b0 of Register Address 0x186F.
The Breaker Product ID is encoded as follows:
•
Product ID = 1 – b15 .. b10 of Register Address 0x186E;
•
Communication Version = 1 – b9 .. b6 of Register Address
0x186E; and
•
Division Code = 32 – b5 b0 of Register Address 0x186E.
5.6. Snapshot Energy
The PM3 Modbus Module supports a control command to cap-
ture energy. A write to Register Numbers 2911 (Address 0x0B5E)
and 2912 (Address 0x0B5F) using Function Code 16 (0x10), Write
Multiple Registers, is used for this purpose. The Modbus command
registers and assignments are shown in Tables 20 and 21.
ote: N
The effect of this command is the same as the Snapshot Energy com-
mand (see Section 5.7).
